Tb all whom itmay concern."

' Be it known that we, DAVID T. SHARPLES and LAWRENCE P. Snanrnns, citizens of the United States, residing at West Chester, in 5 the county of Chester'and State of Pennsylvania, have invented certain Improvemeats in Milking-Machines, of which the fol-lowing is'a specification.-

. Ihis invention has, as a primary ob ect, rovision of a; portable milking machine, pre embly comprising a motor, pum nnlk reservoir and connections, of s1mpe, unproved and efli'cient character, the specified arts' bein -moun,ted one carrier or truck in the pre erred form of the construction.

Practical milking machines, heretofore placed upon the market, have been open to the'ohjeetio'n that they are too cost -for dairymen of small means'and small er ds, particularly because of the neeessity for in stallin an extended'system of fixedparts, the-flee wofflexibility and inabihtyt o make ehangesa'eadily, The present invention is designed to obviate these defeetsybe ng of sueliiighara'eter that it is COIIIPRI'IltlVGly'iDGX- pensive, uires'no installation and can. he moved in "i s entirety from place to place ve readily.

i he'character-istic features of the 1nvention are fully disclosedin the following desei'i tipn and'the accompanying drawings in'i lustr'a'tion the of. I 7

The motor 3 is provided with a shaft 3 having apulley 3" thereon and the pump 4 is provided with a shaft 4- with a pulley 4" thereon, the pulleys being connected by a belt 8 held to proper tension by the tight-ener 8, through which the motor operates the pump. p

The crank shaft 4", which acts through recess 1" to receive the body j the eonnerting rod or pitlnan -t to reciproeate the piston 4 in the ryl-inder 4", is'pro ruled with a .worm i; and a shaft 9, w iirh so -is juurnalod in a hearing 9 and carried by a step'beariug 9", is provided with a worm or helical gear 9" which engages the worm.

The valve 14 is provided wlth'the peripln I the valve 13' closing auto'inat-ic'illy to hold eral port or passage 14", which is in coiistant communication with the vacuum chamber 10 through the port or passage 10? and is and with the longitudinal passage .14,

which is in constant col'nmunication with the atmosphere through the ports 14 .and-is adapted to communicate through its branch passages or ports 14 and H with the'po'rt 10".

The conduit 11 comn'mnicates with the bored arm or conduit (3, having the hinge or flexible connection 1 with the journaled cap 5 of the standard 5, this arm having the branches 6" which are controlled by the stop cocks 15. Flexible tubes 16 connect the branches (5" with the branch tubes 16", which latter communicate with the teat cup chamhers 17 formed by tlizrshells 17 and the iexible linings ii". the arm 6 being provided with the books 3" on. which tluteat cups can be hung.

Flexible tubos .18 are coun rtcd with the teriors of thc respective linings l7", and .with the branches-l1! of a fixture lfl' which is car riod on the arm I The branches 1! co n- ,munirate through the fixture. under control of the stop cocks ill, with the conduits 11), which are carried on the arm 6 and have. the llcxiblc couplings if)" for connecting them llokihly and dctai-hably with thenipplcs 7 of tho lu-rlm'tically scaled cani', the m nmunication through the nipples bring controllablcby the valves 31.

Iience tie exterior of'the teat cup lining 17", through the connection of the portlO" bythe'c'onduit 11. with the chamber 17, is subject to the pulsating effect due to vacuum, atmospheric pressure, superiorv pressure and atmospheric pressure applied in sequence by the action of the rotary valve or pulsator.

As the milking machine, in its entirety, is readily transported as a unit, and as the milking arm is movable about both a horizontal and a vertical axis sothat itlcan be turned out of the way when not in use and to. any desired position forthe application ofthe teat cups to use, such machine is readily placed at any desired position, convenient for milking, the machine being 35 adapted for milking cows in pair's.
